Kerberos authentication fails with `kinit` on macOS

[Seha16]

What happened?

Kerberos authentication fails when I try to connect using kinit on macOS. Even when I enter kinit user@REALM.COM and the correct password in the app, the connection still does not succeed.

I normally establish Kerberos connections in DataGrip for this service through VPN and by running kinit in a separate terminal session. However, when I try to connect to the database using Kerberos in TablePro, the app reports that the credentials are incorrect. This suggests something is wrong with the Kerberos authentication flow.

Steps to reproduce

1. Connect to the VPN required for database access
2. Run kinit user@REALM.COM in a terminal and authenticate with the correct password
3. Open TablePro on macOS
4. Create or edit a database connection using Kerberos authentication
5. Attempt to connect

OR

1. Connect to the VPN required for database access
2. Open TablePro on macOS
3. Create or edit a database connection using Kerberos authentication
4. Enter user@REALM.COM and the same password in TablePro
5. Attempt to connect

Expected behavior

TablePro should authenticate successfully with Kerberos and connect to the database when valid credentials have already been obtained through kinit.

Database type
